I liked Tom (B/but Tom didn't like me(.))

[Sped Tiger]

Please, members, help me with this (I'd really be grateful to you): I have leant that we have to punctuation the information enclosed in parentheses only when those parentheses make a complete sentence, and all the examples provided showed the parentheses at the end, so I have a question now: If we have some parenthesis information that make a complete sentence but is at the middle, do we capitalise the first word and punctuate the parenthesis information?
Examples (which are correct?):
a.a. I liked Tom (But Tom didn't like me.) when we first met.
a.b. I liked Tom (but Tom didn't like me) when we first met.
b.a. If the verb ends in -oe, the final -e is never to be removed (Which, truthfully, I've found out all by myself.): shoe - shoeing, canoe - canoeing.
b.b. b. If the verb ends in -oe, the final -e is never to be removed: (Which, truthfully, I've found out all by myself) shoe - shoeing, canoe - canoeing.

We put something in parentheses (brackets) when providing additional but nonessential information.

As for your example sentence, I would say: "When we first met I liked Tom, but he didn't like me."

a.a. I liked Tom (But Tom didn't like me.) when we first met.
a.b. I liked Tom (but Tom didn't like me) when we first met.

I don't think many native speakers would produce a.b.

b.a. If the verb ends in -oe, the final -e is never to be removed (Which, truthfully, I've found out all by myself.): shoe - shoeing, canoe - canoeing.
b.b. If the verb ends in -oe, the final -e is never to be removed: (Which, truthfully, I've found out all by myself) shoe - shoeing, canoe - canoeing.

I am reluctant to mark b.b correct. It is extremely unnatural.

@Sped Tiger Say:

If the verb ends in "oe" the final "e" is never to be removed, for example: shoe, shoeing; canoe, canoeing. (I found that out in my own.)
